Of bacteria and scientists have created gold material of the future

Mankind is not yet building spaceships, resembling giant living organisms , in science fiction , but like already seems to be in the offing. Researchers at MIT have developed a material of the future - something that has the properties of living and non-living substances.

In short , the engineers took the bacterium E.coli ( Escherichia coli ) , capable of producing a biofilm (a, a pink , you can see in your bathroom , if rarely do cleaning) , and " forced " her to structure using non-living materials - such as gold nanoparticles and quantum dots . As it turns out , if you add in the process of building a biofilm peptides , they , in turn , will capture foreign elements and synthesize new molecules already using them .
As a result, scientists have turned out like "live" with the new material for her properties - conductivity or light emission . A programming bacteria and changing environmental conditions , the engineers were able to change and control the properties of the substances.
